Globjects

• $fh->remember('hippo') will save the current position under the key hippo.

        sub remember {
          my ($self, $key) = @_;     # $self is a GLOB reference
          *$self->{$key} = tell $self;
        }

• $fh->gobackto('hippo') will return to the saved position.

        sub gobackto {
          my ($self, $key) = @_;
          seek $self, *$self->{$key}, 0;
        }

• Future reads from the `filehandle' will continue from the old position
